It’s disabled by default, but I had no idea this was added.
Firefox mobile users started noticing something peculiar this week when sharing links to WhatsApp. After hitting that share button, their messages were getting an unexpected tagline: “Sent from Firefox 🦊” with a direct link to the Mozilla app store listing.
The feature appeared quietly, with no fanfare or announcement from Mozilla.

If that’s where the family chat is, I won’t protest until everyone else moves to Signal or something. It’s a minor miracle we could get both parents to start using the same one platform back then. You add a simple recolor and they feel like an Armenian in upper China with a map of Congo written in Hebrew.
Also, work chat.
I know it’s extremely popular in a lot of places, often the default over even phone numbers. I am in a place like that.
But I refuse. Nothing could get me to participate.
Why did you push so hard to get family to chat? If mine don’t, it doesn’t matter that much. We can still call or use Jitsi or even worse case scenerio facetime.
My older family never are going to chat, and I have no problem with that.
The younger family all switched to signal. That was easy.
Where… where did you get this from? I didn’t push so hard to get my family to chat. In fact, I didn’t push my family to chat. In fact, I wasn’t even the one creating the group, but when most of my family is there already, and I get added to the chat I won’t leave it just because I refuse to. And by the time I had WhatsApp already.
(EDIT: I read back and I kind of understand why you thought so. We got the parents to use same platform once most people were in it already. I didn’t take part in creating the group or choosing the platform, but my siblings and I put some effort in getting our parents to use the same thing, indeed.)
Not out of personal choice. That was the means to communicate at work. I’m glad if it’s not required by your employer, but that was a requirement where I work. It’s like using whatever app/program/tool at work: if that’s what they use for communication (and expect you to do the same), you can’t just say “I won’t partake, everyone can bugger off”.
I’m happy if you have the freedom to pick your own tools for everything, but not everyone can. It doesn’t mean I like it or that I support it.
